On the third floor of the Night Charm Bar, in a private room.
Black Dream is an illegal dream simulation strictly cracked down upon and prohibited by the "Dream Monitorea" For ordinary people, the main source of access is through black market dealers acting as "middlemen."
However, with Keyji using his background and connections, he could bypass the middlemen and directly obtain the product face-to-face from the "manufacturer."
Renji and the others didn't have to wait long, perhaps just about fifteen minutes, when the door of the private room was roughly pushed open. A group of four or five grim-looking men and women quickly entered, with the last one, a female member with a tattoo resembling a "black flame" on her left arm, closing the door behind them.
